Mirror a web site with wget

In order to mirror a web site for offline use or preservation purposes, wget is the tool of the day:

wget --mirror --convert-links --adjust-extension --page-requisites --no-parent <URL to the website>

 The options are as follows:

• --mirror: recursive download and other useful options
• --convert-links: change links to relative links for offline and local viewing
• --adjust-extension: fixes extensions when they don't match the type of their content
• --page-requisites: makes wget download all necessary files to display the web pages (e.g. style sheets, inlined images, etc.)
• --no-parent: only download pages below a certain hierarchy

Before using, make sure you have the right to mirror the said web site. Using too much bandwidth or making too many requests in a certain time might get you blocked.
